generator remains 1dBm.
Setting format:
[:SOURce]:POWer:REFerence <value>
Query format:
[:SOURce]:POWer:REFerence?
Parameter:
<PowRef> Ampl Ref.
Range: 0dBm [-135dBm
，
+30dBm].
Example:
:POWer:REFerence -10dBm Ampl Ref is -10 dBm.
Reset status:
0dBm

[:SOURce]:POWer:REFerence:STATe <State>
Function:
This command sets the state of Ampl Ref Switch. When the power reference switch is
ON and the power reference value is not zero, if the power level of the signal
generator is changed, the power value displayed in the power display area will be
based on this power reference. For setting power reference, see the command
―
:POWer:REFerence
‖; when the power reference switch is OFF, the power value
displayed in the power display area will be the actual CW output power of the signal
generator.
Setting format:
[:SOURce]:POWer:REFerence:STATe ON|OFF|1|0
Query format:
[:SOURce]:POWer:REFerence:STATe?
Parameter:
<State> Boolean data is as follows:
ON | 1: Ampl Ref is turned on,
OFF | 0: Ampl Ref is turned off.
Example:
:POWer:REFerence:STATe 1 Ampl Ref is turned on.
Reset status:
0

[:SOURce]:POWer:STEP <PowStep>
Function:
Set the step value of the power. After setting this value, for setting CW power of the
signal generator, see the command ―
:POWer[:LEVel][:IMMediate][:AMPLitude]
‖. When
changing the power by UP|DOWN, the power variation will change based on the
variation of the current set step value.
Setting format:
[:SOURce]:POWer:STEP <value>
Query format:
[:SOURce]:POWer:STEP?
Parameter:
<PowStep> Ampl Ref.
Range: 0.10dB [0.01dB
，
20dB].
Example:
:POWer:STEP 1dB Ampl Step is 1 dB.
Reset status:
0.10dB
